Avoiding five charging methods to prevent battery damage
In fact, most of the cases where the battery does not last long are due to overcharging, and only by developing reasonable charging habits can electric vehicles run longer and have a longer lifespan. Here are five charging methods to avoid, preventing batteries from overcharging.
- 1.Avoid using fast charging stations
Many drivers often go to roadside fast charging stations for convenience. However, using fast charging stations can cause the greatest damage to the battery. Why is this so?
Fast charging stations for electric vehicles operate on high currents. For example, a commonly used 48V battery may reach 80V in a fast charging station. Prolonged operation under heavy loads accelerates the aging of the battery plates, which can shorten the battery's lifespan and affect its performance. It's worth noting that if battery damage occurs due to the use of fast charging stations, it is considered human-induced, and battery manufacturers generally do not provide warranty coverage for such cases.
- 2.Avoid overnight charging
Just as using roadside fast charging stations is for convenience, many electric vehicle owners also have the habit of charging their vehicles overnight for convenience. However, prolonged charging can cause irreversible damage to the battery. Why is this so?
Although modern chargers have charging protection mechanisms, there is still a small current flowing into the battery after it is fully charged, known as trickle charging. Prolonged trickle charging can damage the battery irreversibly, shortening its lifespan. Therefore, charging time should be controlled to within 8 hours to prevent overcharging.
- 3.Avoid using incompatible chargers
Many households nowadays have more than one electric vehicle, but many owners often use incompatible chargers, which can seriously affect the battery's lifespan. Why is this so?
For example, using a 72V charger for a 48V electric vehicle may cause the battery to swell and eventually become unusable. Conversely, using a 48V charger for a 72V electric vehicle may lead to undercharging, reducing the vehicle's range. It's worth noting that some cheap chargers, priced at just a few dollars, should never be purchased. These low-quality chargers lack safety guarantees and can not only affect battery lifespan but also increase the risk of electric vehicle fires.
Similarly, for convenience, many electric vehicle owners carry the charger with them while driving, but this habit can also seriously affect the battery's lifespan. Why is this so?
Since the electronic components on the mainboard of electric vehicle chargers are soldered, the charger's internal electronic components can become loose due to vibrations from bumps and potholes encountered during normal driving. This can result in unstable currents and loss of protective functionality, leading to battery damage.
